I found a Clen FAQ on anabolicextreme.com, issue 70.
Clenbuterol FAQ
Check it out. Taurine at 3-5g is a must according to the article. As far as the Ketotifen goes, it will extend the use of Clen but "The downfall of this drug is its ability to induce
extreme hunger is some people, which is not a desirable state to be in when dieting. "
Hope that helps.
